To all whom t may concern;

Be it known' that l, JoHN NEwirANiN, a c itrzenof-the' United States of America, residing atBrooklyn, vin -the county of Kings and YState vof New York,l have invented 4certain new and useful, Iml'iroveme'nts in Roller- Bearings, of which the following is a specifil parts.' .These perforations serve for the re,-

ception of balls e' (Figs. 5-8). The halls are insertedinto the perforations prior to cation.

' The present invention' pertains to roller bearings of the kind specified in my Patents NQS. 9e9,7e3,i,003,i95 and i,o0i,e73 'and particularly tothe spacers, and has for its Object to impro-ve, the i(':onstruction of the roller bearing with the view of reducing the cost of'manuf'acture thereof.

' My invention `is fully illustrated inthe struction of my new spacer, 'Fig. 1 showing the-first'/'stage of apartof a spacer; 141g. 2

The roller bearing, according to the p atents above referred to, are composed of rollers and loose blocks interposed between the rollers and serving as spacers. Experiment A`has shown that theconstruction offthe loose blocks or spacers is great-ly simplified and cheap'ened when carried out in accordance with the vpresent invention.

Referring toFigsylS. the spacers are I shown to he composedof two'separate uniform pieces a, of which each is punched 'of sheetvmetal, so as to lform an enlarged middle portion a andreduced end portions'ag.

' One end portion is provided vwith a tenon b and theotherfend portion .with a mortise c, so that when the two parts are. put on top of one another, the teiion of one will engage speciacaaon of Letters Patent.; PatentedN 2, 1915.

The ,upperand lower extensions 'a3 of the,

The curvature 0f said'extensions 1s made to conform with the cylindrical surface of the' rollers (Figs. 9 and 10) fr. l tenons to join the twoparts andthe bending or 'curving ofthe extensionsof the 'middle portions may be accomplished in one 'operation. '.On. the adjoining inner surfaces of 'both parts I provide furrows f, through" site directions and their outer surfaces are lso which any'lubricating material which may be placed inthe space s betweenthe curved extensions ofthe two yparts may find its wayv tothe rollers and other workingparts (Figs.
